55 tion with re T all whom it may concern:

Be it known that 1, JOHN C. Bureau, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Perforators; and I do hereby declare the following to be .a full, clear, and exact description of the same, such as will enable others skilled in I 'the art to which it appertains to make and use the same. r

.My invention relates to improvements in perforating machines, and more particularly The objects of my invention are to reventrepeating of characters due to fa' ureof the clutch mechanism to work properly, and to simplify the feeding mechanism of machines such. as illustrated and described in my said former application.

The machine described in my said former pplication, and illustrated herein, in so far Sis is required for explanation of the present invention, is adapted for perforating paper strips or ribbons for the Wheatstone and similar automatic telegraph systems, and comprises (a) punching mechanism; (1)) paper feed mechanism; (0) a key board comprising finger keys and selecting means operated thereby and controlling approriate devices for the punching and paper eed mechanisms, whereby at each operation of a finger key, the proper combination is set up to punch this character in the srtip, and by w iich space determining means are operated to regulate the feeding of the paper strip to correspond with the space occupied byeach character so punched; ((1) rower mechanism inde cndent of but contmlled by the keys, whereby the actual work of feeding the paper and of punching is performed by a motor, prefcrablr a continuous'ly running motor.

I will now proceed to describe my invencrence to the accompanying zontal section of t e main drawings and will then point out the novel detail side view of the key boar mechanism the frame of the key board, the selecting bars, and certain other parts being sectioned; view and partial hori 'ortions of the Fig. 4 shows a to punching and paper feed mec anism; .Fig. 5 1s a detail top view of a portion of the aper feedin device; and Fig. 6 is a detai .face view 0 a portion of the papenfeeding device. Fig. 7 is a detail rear view and partiaLsection of the paper fee-ding mechanism; and

'Fig. '7 shows in detail parts of the stop-pin 8 shows a top 75 adjusting mechanism. view of the gearing and clutches throug which the punching and; aperfeed mechanisms are driven; Flg. 9 liows a front elevation of such gearing and clutches and Fig. 10 shows a deta l to view of the clutch through which the uncliing mechanism is driven. Figs. 11 an 12 are respectively a detail side view and a detail end view of an alternative construction of a part of this clutch releasingdevice. Figs. 13 and 14 are respectively'a transverse section and an axial section of the frictional driving device of the feeding mechanism. Fig. is a detail perspective view of the clutch-o ening cam 73.

In-thc following escription I will. use so far as practicable the same reference numerals as are applied to the corresponding parts shown in the drawings of my said prior application Sr. No. 349, 967.

In said drawings, 1 designates generally a key board, 2 designates generally a punching mechanism, 3 designates generally paper feed and spacing mechanism, 4 designates a driving motor and 5 designates generally transmission mechanism. com rises finger keys 6 and corresponding key overs 7, each operating, through suitable selecting lugs hereinafter mentioned, certain of two series of selecting bars, 8 and 9.10-

catcd beneath the key board. These bars are mounted upon pivoted links H) (Figs. 2 and. 7) so as to be capable of moving freely u and down while remaining horizontal at all times; and springs 11 countcrliii-lance the weight of these bars and links and tend to The key board hold the same upward. The bars of series 8 control and, when operated, effect the adjustment of, certain pins of the paper feed and spacing mechanism 3, whereby the distance the paper strip is to be fed is regulated.

The bars ofseries 9 control, and when oper-' ated, effect theoperation of, certain punch-' lar bars of series 9 which that lever is to operate, and is further provided with a similar lug 13 located over the particular bar of series 8 which that lever is to operate. For

' operatin the clutch mechanism hereinafter describe "by which the power driven member of the punching mechanism and mechanism for ad usting and restoring sto(ps of the paper feed mechanism are 0 erate I have rovided in the machine s own in these rawings, a universal bar 14 located beneath and at right angles to the selecting bars 8 and 9 and, like said bars, mounted. upon parallel links 10, and this bar-is provided with a hooked extension 15 arranged to engage a transverse trip-operating bar 16 (Figs. 3, "8 and 9) arranged transversely with respect to the key levers and, like selecting bars 8 and 9 and universal bar 14, mounted upon pivotedparallel links 10. Itwill be observed that when any one or more of the selectin bars of series 9 are depressed the universal bar 14 will be depressed and will in turn depress bar 16, arranged at right angles thereto, such bar being thereby caused to move longitudinall of itself or to the left of Figs. 8 and 9, as will be seen by comparing said figures.

The punching mechanism 3 and certain devices for setting certain stofpins of the ing to press it into engagement with member 59. A stop 63 (Figs. 8 and 9) pivoted at 64,

normally engages a lug 65 carried by this clutch member 61 and holds it out of engagement with clutch member-59, but when universal bar 14 is depressed by the depression of a finger key and causes bar 16 to move to the-left of Figs. 8 and 9, a hook 67 connected to said bar 16 and normally in engagement with a trip 68itself normally in engagemnet with one end of stop 63, drags said trip 68 out of engagement with sto 63, thus ermitting the spring 72 of sai stop to pu 1 it u ward, so freeing lug 65, and permitting c utch member 61 to be forced by spring 62 into engagement with clutch member 59, thereby causing shaft 45 to revolve. As the left end (as seen in Fig. 9) of sto 63 en counters hook 67 it depresses said ook,. so as to cause it to release the tri 68, thereby permitting the spring 71 of sai .trip to draw it back into position to engage again the stop 63. On-shaft 45 is a cam 66 which, as soon as said shaft begins to revolve, engages a bell crank extension 631 of stop 63, and thereby positively forces said stop back into position to arrest the lug of the clutch member 61, at the conclusion of one revolution of shaft 45; and as soon as stop 63 is so moved back to position to arrest lug 65, the trip 68 previously released from hook 67, as above described, engages said stop 63 and holds it in such position. In the path of rotation of lug 65 is a s iral throw-out cam 73 which, near the cone usion of one revolution ofthe lug 65, engages the same and forces it gradually away from clutch member 59, thus opening the clutch and at the conclusionof one revolution lug 65 jumps from the end of the cam 73 into engagement with stop 63 and is held thereby.

The construction of the parts is such, it will be seen, that for each depression of. a finger key and consequent release of stop 63 only one revolution of the cam shaft 45 can occur. It is important that onl one revolution of such shaft shall occur or each depression'of-a finger key, becausea second rotation of the shaft will cause a repetition of the operation of the punching mechanism. Heretofore difliculty has been experienced in devising a reliable clutch and tripping mechanism; some forms of tripping devices producing so much frictional drag on the clutch member 61- as to occasionally prevent prompt engagement of the clutch members when the trip 63 is first operated, and some forms of tripping device failing to return the stop 63 promptly enough to arrest the lug 65 at the conclusion of one revolution. In the mechanism above described, however, the

saidcam holds the stop 63 in such position I until ample time has 0. psed for the release of trip 68 and the reengagement of the stop 63 thereby. But notwithstanding the 051- tive action of the cam 66 as described, t mm is no friction whatever between said cam and the bell crank extension 631 at the time when the clutch member 61 is first released, such bell crank extension631 being then opposite the flattened portion of cam 66 and'therefore not then in engagement with said cam. Such bell crank extension 631 is provided with a friction roller 632 to avoid wear between such extension and the cam.

In Figs. 11 and 12 I illustrate an altertively.

native device for returning the stop 63 posi- In this form said stop is provided with a cam extension 633 adapted to be engaged by the lug When stop 63 is first released by the action of stop 68, as previously described, and is drawn upward by its spring 72, the cam extension 633 is raised into such position that, as the lug 65 revolves, such extension will be engaged by-,

such lug and depressed thereby, so returning stop 63 to its arresting position. In this form of the device a stop screw 634 is provided to regulate the rise of stop 63, so that the cam extension 633 may not be in engagement with the clutch member 61 at the in stant when said member is moving'into engagcment with clutch member 59.

From the above it will appear that in both forms of the devices illustrated I have provided positive means for returning the stop to its arresting position immediately after the shaft begins to rotate, and for holding the stop in such position until ample time has elapsed for the return of the trip 68 to position to engage and hold said stop; likewise that I have avoided any friction of the stop against the clutch member 61 tending to retard movement of said clutch member into engagement .with its companion clutch member 59.

A further feature of my invention relates to means for operating the restoring arm and other parts of the paper feed mechanism. For the. understandingof such im irovement I will describe briefly the said feeding mech anism.

The paper strip, 22, is drawn from a-reel and passes over guide rollers 23, and between retarding tension and guide rollers 24 and '25, and through the punch head 30 bet-ween the die plate 31 thereof and the punches 27 of said punch head and thence around toothed 'l wheel 7% provided with teeth 7?) and -uh a lar e number of sin iins 8O arran ed E l l to slide vertically in said wheel and surrounded by spiral springs 81 which act as frictional drags. to hold said pins in any position in which they may be set against the influence of gravity or vibration. This wheel is rotated intermittently to feed the paper forward between the punching operations, and rotates different distances accordingto the space occupied on the stri by the charactor to be punched. This (istance is determined by raising different of the stop pins according to the distancethc wheel is to be ermitted to rotate; each pin so elevated eing' brought, by the rotation of the. wheel, against a shoulder 89 on a plate 82 located immediately above said wheel. When a pin so contacts wit h said shoulder the motion of the. feed wheel is arrested until said pin is depressed (by nlimns to be described presently) and ancilu-r pin elevated toregulate next character.

The appropriate stop pin 80 is elevatediby means of one or another of the arms 101 actuated through connecting mechanism b one or another of the selecting bars 8 beneat the key lev ers 7. Each key let er is row-ided with a projection 13 (Fig. 3) locate so that when said lever is de ressed one or another of the bars 8 will be epressed; such projection being located over the particular bar 8 corres on'ding to the distance the pa er strip shoul be fed forward for the particulhr character corresponding to that key; Each bar 8 when so depressed operates a pivoted arm 103 (Fig. 7) and, therethrough, the corresponding arm 88. .The front ends of these arms 88 are immediately above a reciprocat ing driver 184; but said arms 88 have in their front ends notches 106 which prevent said drix er 104 from raising any oneof said arms 88 unless that arm has been ushed forward,

as it will be if its correspon ing selector'bar 88, the ends of .said pushers being beneath the row of stop pins 80 of the said wheel 78. Each pusher has, over the particular arm 88 which is to operate it, slug 101" (Fig. 7')

dee enou h to cause said pusher to beoperater by-t at particular arm 88,- but by ho other. The'several lugs 101 grow progressively deeper from thepivots of the pushers out-ward, so that the pushers are a] raised the same distance notwithstanding the different distances of the several lugs 101' from the it ots of said pushers.

T e reciprocating driver 104 is raised each time the shaft 45 revolves by a cam 93 on said shaft and a follower 95 transmitting motion to said reciprocating driver 104, through a spring 105. The actual work of raising the stop pins 80 is performed; therefore, by the power driven shaft 45 and the parts operated by the cam 93 thereon; and the only work done by the key levers, so far as the raising of these stop pins 80 is concerned, is, the moving of an appro riate arm 88 into position to be engaged by t e'reciproeating river 104. i

After the stopping of the feed wheel 7 8 by enga ement of one of the stop pins 80 with the shou dcr 89 of plate 82, and after the punching of the corresponding character in the paper by the action of the punching mechanism, said pin 80 is depressed to normal position and said wheel is permit-ted to rotate onward until again arrested in the same manner by encounter of another pin 80 with said shoulder-.89. lhe depression of the pins 80 is effected by a restorin and 90 carried-upon a'vcrtically mowable r0 Q1 (Fig. 7), said arm 90 having also some slight pivotal movement in a horizon tal plane and being-normally held as far to the left of Fi 1, by a spring 92. as a slot 84 in plate 82 wil permit; in which position it'is directly over the'end of that stop pin 80 which at the time is. in engagement with shoulder 89. Rod 94 is arranged to be raised and lowered by the same cam 93 and follower 95 which operate the reciprocating driver 104; and the shape of the cam 93 is such that after the punching of a character in the strip (which punching is effected the action of cam 44 on shaft 45 and its fol ower 42 on the punches within punch head 30, i i mediatelyshaft 45 begins to rotate) the follower 95 raises rod 91, the arm 90 being drawn to the right (of Fig. 7) by spring 92 as soon as said arm 90 clears the top of the stop pin 80 then in engagement with shoulder 89;

- the end of arm 90' being thus brought dia when rod 91 descends again.

rcctly over the top of such pin 80. Near the end of the revolution of shaft 45 cam 93 permits follower 95 and rod 91 to descend, so

pushing down said pin 80 and permitting the eedwheel'to rotate until arrested by engagement of another pin 80 previously elevated with said shoulder 89. As shown particularly in Fig. 5, the end of arm 90 just clears shoulder 89, and each in 80 when in engagement with said shoulder rests partly against the shoulder and partly against the end of said arm; for which reason it is clear that -when. said arm is raised above the level of such pin 80 as it will be-when rod 91 is ele., vated by follower 95, it will spring over the top of such pin 80 ready to depress the same In order that feed wheel 7 8 may rotate in this intermittent manner, said wheel is driven through a yielding' driving device. Said wheel is mounted on a verticallshaft 107 (Fig. 7) driven b s 'iral earing 108 from a shaft 109 itse f iven rom t e motor 4 by a gear 110 mounted on said shaft 109 and in frictional driving connection therewith'through a spiral spring 113 (Figs. 13 and 14) connected at one end to a plate 114 and provided at the other end .with a friction cushion 115 rubbing against the inner surface of the rim of said gear 110; said late 114 carrying one member of a jaw clutc 111, the other member of which isarranged to drive said shaft 109, but is mounted to be moved longitudinally thereon by means of a key 112. This clutch and key are provided to permit unclutching of the feed wheel 78 from the driving motor to facilitate threading of the paper strip through the machine. A pin 117, carried by said key is arranged to be thrust thereby through one of a series of holes 116 in disk 114 whenever said key is operated to open clutch 111; the disk 114 being thereby locked so as to prevent. uncoiling of the spiral spring 113.

The 0 eration of this machine is as follows: T he motor 4 being in rotation, when one of the finger keys 6 is depressed, a corresponding combination of selecting bars 9 is depressed, also that selecting bar of series 8 which will cause the paper stri to be fed forward the distance correspon 'ng to the s ace occupied by the character of such key.

hose bars of series 9 which are so depressed operate corresponding fingers 32 and 33 ig. 2) so as to bring them opposite the ends of the corresponding punches 1n punch head 30 and-at the same time universal bar 14 beneath said bars 9, being depressed, depresses bar 16 and so causes it to be moved to the left of Figs. 8 and 9, so pullin out trip 68 and causing stop 63 to release lug 65 of clutch 58 and )ermit said clutch to close. Rotation of shaft 45 then be ins and cam 44 on said shaft operates its ollower 42 and causes said follower to operate the selected punches and so punch in the paper strip 22 the holes corres onding to the particular charactefof the inger key 6 which has been depressed. describe particularly the arrangement of the punches and punch selecting devices, as these parts are not directly involved in the resent invention. The punches of punch ead 30 having been'operated and having.

I do not herein illustrate and,

retired again, and cam 93 having meanwhile raised rod 91 so as to cause arm to spring over the topof' that stop pin 80 which is at the time holding feed wheel 78 stationary, said cam 93 then permits follower 95 and rod 91 and arm 90 to descend, so depressing that pin 80 which has been holding wheel 78 stationary and permitting wheel 78 to rotate,-

so feeding the paper forward. At the in stant when the articular finger key 6 operated depressed the appropriate bars of series 9 as'above stated, the particular bar of series 8 also depressed as above stated, caused its corres onding arm 88 to move out over the end 0 the reciprocating driver 104 (Fig. 7

and when cam 93 caused rod 91 to rise it also' raised driver 104, thus elevating another of pins 80. This all takes lace before the depression of that pin 80 w ich has been holdmg the wheel 78 stationary, as above described. Wheel 78 now rotating, that pin 80 which has just been raised by the action of the finger key-6,. arrests said wheel .78 when such pin 80 comes in contact with stop shoulder 89. A cycle of o eration has not been completed, the whee 78 has fed the paper forward a distance corresponding to the space on said strip occup1ed by the qharacter just punched, and the machine is 111 readiness for the depression of the same or any other finger key 6 and for the commencement of a new cycle. At the instant when bar 16 was pulled to the left as above described, and stop 63 caused to release the clutch member 61, friction roller 632 was opposite the flattened portion of cam 66 and so not in engagement with said cam, there- "fore offering no resistance to the movement erases of clutch member 61 into engagement with clutch member 58. When shaft 45 is rotated a few degrees, however, cam 66 engages said friction roller 631 and moves stop 63 positively into position to arrest thr lug 65 at the completion of one revolution of the shaft 45. Trip 68 having previously been released from-hook 67 holds stop 63 in such osition. The paper strip after passing the eed wheel 78 is led out through'a guide 26, passin across and above the key board, that face 0? said guide which is toward the key board being open so thatthe operator may read the message punched.
